Germany's Eurovision Song Contest entrant has rejected calls to quit after her producer was accused of foul play in the selection process.
The Sports Palace in Kiev will host the contest
Gracia's producer David Brandes has admitted buying up 2,000 copies of her single to ensure it would be in contention for Eurovision selection.
Other German singers have complained it was unfair that she was selected because of inflated singles sales.
"I haven't done anything wrong," said 22-year-old Gracia.
Gracia was a contestant on German Idol two years ago but failed to capitalise on her exposure, fading after just one single.
"I'm guess I'm jinxed," she told Bild am Sonntag newspaper.
"Every time things look like they're going well for me someone comes along with a frying pan and whacks me on the head."
The contest will be held in Ukraine after Ruslana's win last year
Mr Brandes said he bought 2,000 copies of the song Run and Hide to ensure it would register in the charts and qualify for Germany's qualifying stage.
Despite winning a public vote to go on to be Germany's entrant there have been calls for her to step down in the wake of Mr Brandes' admission.
The producer, who is also behind the contest's Switzerland entrant, is adamant he bought the singles only to counter other producers who did the same for their artists.
"Morally, I think it's okay to do it," Brandes said.
Despite this he has been banned by NDR Television from going to contest in Kiev, Ukraine, as part of the German contingent, although Gracia will not be affected.
He and his artists have also been barred from the singles charts for three months.
